DistributionSandhills and southern Coastal Plain; scarce on barrier islands. Ranges north only to Greene, Harnett, and Moore counties.

Coastal Plain, NC to southern FL and southeastern LA.
AbundanceGenerally fairly common over the range. Individual populations may have abundant plants. The website editors suggest a State Rank of S4.
HabitatXeric sands and nutrient-poor sandy soil with little competition: sandpits, scrapes, sandhills, poor fields, oak scrub on Carolina bay rims, interdune flats.
PhenologyFlowering and fruiting August-October.
IdentificationThis weak-looking grass grows 1-2 feet tall, a few to several stems from the base. The leaves are at most 2 mm wide. The terminal inflorescence is composed of 3-7 well-spaced spikelets, usually purplish and 2-5 flowered. It is very similar to Purple Sandgrass (T. purpurea), but the stem internodes are pubescent (vs. glabrous internodes in that species).
